I'm in the process of rebuilding a 5.0 SC engine and I have a decision to make. As I'm not a machinist by trade I thought I would float this out there to those who have more experience in this area than me.
Upon disassembling my engine, I discovered I have the original style M10 size bolts. A little later LR upsized these bolts to M11. I have read several threads about guys boring and re-tapping the original M10 holes to accept the newer M11 bolts, but I wonder if it's worth it?
I have run into issues boring and re-threading blocks before, and I'm wondering if it's riskier to use the smaller M10 bolts or to machine, helicoil and use the M11 bolts?
Full disclosure, I plan un upping the HP of this engine as soon as I can afford it...probably looking to make close to 600HP or so. (Assuming I can find someone to re-VIN my SC ECU so I can fit it into my LR4....but that's a whole other thread!).
Anyone out there done this before? Pros - Cons?
